Small Neurotransmitters
{"Image DocumentName": "Small Neurotransmitters", "Image ImageDescription": "1. Amino Acids. Glutamate/ Gamma-aminobutyric acid (GABA) MAJOR NTs in the CNS/ All over. 2. The Monoamines. Catecholamines. Dopamine- DA- reward/movement. Norepinephrine- NE \u2013sympathetic. Epinephrine-released from adrenals. Indolamines. Serotonin -5-HT. 3. Acetylcholine (ACh) Glut is major excitatory NT in CNS/ GABA is major inhibitory. Glut- long axon neurons. GABA is primarily in interneuron (in one nucleus--- in between the input/out put neurons in one nucleus.) In a way, you can can anything else a neuromodulator\u2026 because these are the major NTs in the CNS, all the rest regulate whats going along the GABA or glutamatergic connections. 2. acetylcholine: contracts skeletal muscles/ ANS. Important in Alzheimer s disease in basal forebrain (Ach decreased)./ interneurons. 3. Biogenic amines. Catechol/indol refers to their molecular structure. Localized in small cell groups/ clusters within the brain. Not widespread/ dispersed like the amino acids, but are equally important. NO SMALL EFFECT. Axon collaterals to cortex/ high order functions\u2026\u2026 Da----- for example---- involved in addiction. VTA--\uf0e0 NAc. This pathway which utilizes DA transmission is vital to almost all kinds of addiction.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
